Comparison of Parameter Estimation Methods Based on Two Additive Biomass Models with Small Samples.

Publication Type: Academic Journal

Source(s): Forests (19994907). Aug2023, Vol. 14 Issue 8, p1655. 14p.

Abstract: Accurately estimating tree biomass is crucial for monitoring and managing forest resources, and understanding regional climate change and material cycles. The additive model system has proven reliable for biomass estimation in Chinese forestry since it...

A Coherent Integration and Parameter Estimation Method for Constant Radial Acceleration Weak Target via SOKT-IAR-LVD.

Publication Type: Academic Journal

Source(s): Remote Sensing. Sep2023, Vol. 15 Issue 17, p4227. 17p.

Abstract: In order to enhance the detection and parameter estimation capacity to the maneuvering target with complex motions, a low complexity coherent integration and parameter estimation method named SOKT-IAR-LVD is proposed in this paper. In SOKT-IAR-LVD, fir...

Monopulse Parameter Estimation for FDA-MIMO Radar under Mainlobe Deception Jamming.

Publication Type: Academic Journal

Source(s): Remote Sensing. Aug2023, Vol. 15 Issue 16, p3947. 22p.

Abstract: Multiple input multiple output with frequency diversity array (FDA-MIMO) radar has unique advantages in mainlobe deception jamming suppression and target location. However, if the training sample contains the target signal, it will lead to poor jamming...

Automating Model Comparison in Factor Graphs.

Publication Type: Academic Journal

Source(s): Entropy. Aug2023, Vol. 25 Issue 8, p1138. 23p.

Abstract: Bayesian state and parameter estimation are automated effectively in a variety of probabilistic programming languages. The process of model comparison on the other hand, which still requires error-prone and time-consuming manual derivations, is often o...

Using Epidemiological Models to Predict the Spread of Information on Twitter.

Publication Type: Academic Journal

Source(s): Algorithms. Aug2023, Vol. 16 Issue 8, p391. 15p.

Abstract: In this article, we analyze the spread of information on social media (Twitter) and purpose a strategy based on epidemiological models. It is well known that social media represent a strong tool to spread news and, in particular, fake news, due to the ...

Estimating the Multidimensional Generalized Graded Unfolding Model with Covariates Using a Bayesian Approach.

Publication Type: Academic Journal

Source(s): Journal of Intelligence. Aug2023, Vol. 11 Issue 8, p163. 17p.

Abstract: Noncognitive constructs are commonly assessed in educational and organizational research. They are often measured by summing scores across items, which implicitly assumes a dominance item response process. However, research has shown that the unfolding...

Estimation of Population Parameters of Glossogobius giuris in the Rabnabad Channel, Southern Bangladesh: Implications for Sustainable Management.

Publication Type: Academic Journal

Source(s): Sustainability (2071-1050). Jul2023, Vol. 15 Issue 13, p10172. 15p.

Abstract: The tank goby Glossogobius giuris is a commercially important dominant fish species in the Rabnabad Channel in southern Bangladesh. However, information on the population parameters of this species is not available to support its sustainable management...

A Novel Parameter Estimation Method Based on Piecewise Nonlinear Amplitude Transform for the LFM Signal in Impulsive Noise.

Publication Type: Academic Journal

Source(s): Electronics (2079-9292). Jun2023, Vol. 12 Issue 11, p2530. 19p.

Abstract: In a complex electromagnetic environment, any noise present generally exhibits strong impulsive characteristics. The performance of existing parameter estimation methods carried out in Gaussian white noise for the linear frequency modulation (LFM) sign...

GWO-Based Multi-Stage Algorithm for PMDC Motor Parameter Estimation.

Publication Type: Academic Journal

Source(s): Sensors (14248220). Jun2023, Vol. 23 Issue 11, p5047. 16p.

Abstract: During the design of a wheeled mobile robot, the problem of the proper selection of the parameters of its motor controllers was encountered. Knowing the parameters of the robot's Permanent Magnet Direct Current (PMDC) motors, precise tuning of the cont...

A Structured Sparse Bayesian Channel Estimation Approach for Orthogonal Time—Frequency Space Modulation.

Publication Type: Academic Journal

Source(s): Entropy. May2023, Vol. 25 Issue 5, p761. 16p.

Abstract: Orthogonal time–frequency space (OTFS) modulation has been advocated as a promising waveform for achieving integrated sensing and communication (ISAC) due to its superiority in high-mobility adaptability and spectral efficiency. In OTFS modulation-base...
